WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 297,892, dated April29, 1884.

Application filed February 28, 1884. (No model.)

State of New York, have invented certain new" and useful Improvements inWindow-Shades;

and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompa} nying drawings, which form a part of this specification,and in which- Figure 1 is a perspective view of my improvedwindow-shade. Fig. 2 is a perspective view of one of thesupporting-brackets. Figs. 3 and 4 are detail views of thespring-bracket, and Fig. 5 is a similar view of the pivotbracket.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to window-shade operated by springs ,and itconsists in the improved construction and combination of parts of thesame, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates a cornice, to theends of which the spring-bracket B and the pivot-bracket O are secured,and which is clamped by two brackets, D, secured in the wall orwindow-frame, and forming two projecting lips, E, between which thecornice is held, thumb-screws F passing through the upper lips of thebrackets, and bearing against the upper side of the cornice, preventingthe cornice from slipping out from between the lips. The pivot-bracketG, in which the pivot Gin the end of roller H turns, is provided with aninwardly-projecting base-plate, I, having two longitudinal slots, Jextending from its inner edge, and two fastening-screws, K, pass intothe under side of the cornice, the slots sliding upon them, andtheirheads bearing against the under side of the base-plate, allowingthe bracket to be adj usted upon these screws to accommodate roll: ersof different lengths. The spring-bracket is provided with a base-plate,L, secured by means of screws to the under side of the cornice, and theportion of the bracket projecting downward from the base-plate forms anarrow cylindrical casing or barrel, M, the inner open side of which iscovered by'a recessed plate, N, secured removably to the same. Thebarrel has a central bearing, 0, through which passes the outer portionof a shaft, I, to which 'the inner end of the helical spring Q issecured, the outer end of which spring is secured to the inner side ofthe barrel, in the same manner as the springin a watch or clock. Theouter end of the shaft is preferably square, adapted to be turned by akey or wrench, and a ratchet-wheel, R, is secured upon the shaftimmediately above the spring, and engages a pawl, S, upon the under sideof a cog-wheel, T, which turns and fits upon the shaft. This cogwheelengages a pinion, U, secured upon the face of a cog-wheel, V, and thiswheel meshes with a pinion, W,upon the end of a sleeve, X, which turnsupon the reducedinner end,Y, of the shaft, and which sleeve is adaptedto be inserted with its square or otherwise polygonous end Z into acorrespondingly-shaped per foration in the end of the shade-roller. Whenthe spring is wound slightly so as to give tension to it, and the shadeis drawn down, thevided to hold the shade down at different points ofthe window-frame, as in other spring-actuated roller-shades.

It will be seen that by having the operatingspring inclosed inone of thebrackets, ashade and roller of any construction may be adapted to thebrackets; and it will also be seen that the roller-bearing bracketsbeing secured upon the cornice, and the cornice being held between theclamping-lips of the brackets, which may be secured into the wall orwindow-frame at any distance from each other, the roller may be used ina window in which a roller secured between brackets secured directly inthe wall Having thus described my invention, I claim and desire tosecure by Letters Patent of the United States- 1. The combination of acornice having roller-bearing brackets, with brackets having projectingclamping-lips adapted to clamp the cornice, and having set-screwspassing through the lips bearing against the cornice, as and for thepurpose shown and set forth.

2. The combination, in a window-shade, of the roller, with a brackethaving a longitudinally-slotted base-plate and screws passing throughthe slots, the said slots sliding upon the said screws, as and for thepurpose shown and set forth.

3. The combination, in a window-shade, of the roller, with a brackethaving the end of the roller pivoted in it, having slots in itsbase-plate extending from its inner edge, and sliding with the saidslots upon screws, as and for the purpose shown and set forth.

4. In a widow-shade, the combination of a bracket forming a fiatcylindrical easing or barrcl covered by a recessed plate, a helicalspring secured to the inner side of the barrel and to ashaft turning inthe barrel, a shaft turning in the barrel, having the inner end reducedand provided with a ratchet-wheel, a cog-wheel turning upon the shaftand having a pawl engaging the ratchet-wheel, a cogwheel having a pinionmeshing with the aforesaid cog-wheel, a sleeve having a pinion upon itsinner end, turning upon the reduced inner end of the shaft, and havingits inner end polygonous, and a shade-roller pivoted in a bracket at itsother end, and having a recess or perforation in its end adapted toreceive the end of the sleeve, as and for the purpose shown and setforth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

EDWIN V. WHITAKER.
